Our process: Making vegetable soup.
Narrative description:
Check the recipe. If you have all the stuff you need, proceed. If you don’t, go to the store and buy it. Put a pot of water on the stove. While the water is heating, chop the vegetables. When water is boiling, add vegetables and spices to the water. From time to time, taste the soup. Add seasoning (salt and spices) to taste. When the soup tastes OK and the vegetables are tender, serve it.
The flowchart (next page):
Once you’ve decided to make soup (beginning the process), check the ingredients in your kitchen and pantry. Have everything? If yes, proceed. If no, go to the store. Have everything now? If yes, proceed. If no, curse and go back to the store. Repeat until you finally have everything. (This iterative process is called a LOOP.)
The steps:
The steps in the process:
Once you have your stuff together (previous step), put the water on to boil and chop the vegetables. Is the water boiling? If no, wait. If yes, add the vegetables and spices to the boiling water.

The steps in the process :
After putting everything on (previous step), wait. Taste the soup. Seasoning OK? If yes, continue. If no, add seasoning and taste again. Are the vegetables tender? If yes, serve the soup. If no, wait and taste again. When seasoning is OK and veggies are tender, serve the soup.

Here’s the whole process.
This is OK, but some may think
it’s a bit crowded. Let’s break
it up over three separate pages
using references. These are
arrowhead –shaped boxes with
numbers in them (next page).
Connecting page 1 to page 2, using the

So how do I actually DRAW one of these things?
Use an app:
MS Visio (best, but $$. Buying it solely for this assignment would be like buying a Ferrari to drive the kid to school.)
http://office.microsoft.com/en-us/visio/
SmartDraw (free trial) http://www.smartdraw.com/
MS Word – you’ve already got it! Dozens of tutorials on the Web; Google “MS Word drawing tutorial.” There’s a good one at
Or, just DRAW it! Use a black
Sharpie on white paper. Scan.
